The following life cycle pattern is shown by____
1 Fucus
2 Kelps
3 Ectocarpus
4 Volvox
Explanation:
Given figure represents a haplontic life cycle. It is exhibited by algae like Volvox.

An alga which exhibits diplontic life cycle is
1 Spirogyra
2 Fucus
3 Polysiphonia
4 Funaria
Explanation:
An exceptional case where an algae exhibits a diplontic life cycle is seen in the brown alga, Fucus.

In bryophytes
1 Dominant, diploid, multicellular sporophyte alters dominant with dependent gametophytes.
2 Dominant haploid multicellular gametophyte alters with diploid dependent sporophyte.
3 Both the stages are dominant
4 The plant body shows haplontic life cycle.
Explanation:
Bryophytes exhibit haplo-diplontic life cycle. In this cycle, the dominant, independent, photosynthetic, multicellular but haploid gametophyte is the main plant body. It alters with a dependent, multicellular, diploid sporophyte.

When both the phases of life cycle are multicellular, i.e., haploid and diploid phases
1 Life cycles are called haplodiplontic
2 However, they differ in their dominant phases
3 They are seen in pteridophytes and bryophytes
4 All of them
Explanation:
An intermediate condition, where both gametophyte(n) and sporophyte (2n) are multicellular is known as Haplo-diplontic life cycle. It is exhibited by pteridophytes and bryophytes.
